Gary Barlow is set to take to the stage on this week’s Superstar , performing a duet with the five remaining hopefuls on the show.
The Take That frontman and X Factor judge will play piano for the five contestants as they perform a rendition of the band’s hit Greatest Day on Monday night’s edition of the show.
The move will reunite Gary with Andrew Lloyd Webber, who he teamed up with to co-write the Diamond Jubilee chart-topper Sing earlier this summer.
Gary is one of a number of big name performers set to take to the stage on the show this week.
Opera singer Katherine Jenkins will perform on Tuesday night’s show while Mel C – who is one of the judges – will sing during Wednesday night’s final.
Five finalists remain in the competition following the double elimination of Jon Moses and Jeff Anderson on Friday.
They are perfomer Ben Forster, Voice reject Nathan James, former boy band member David Hunter, Scouse rocker Rory Taylor and West End performer Roger Wright.
Nathan James is currently favourite to win the competition and land the lead role in Jesus Christ Superstar on its forthcoming arena tour.
